Goliath Roofing Systems by CGT: One Billion Square Feet of Proven Protection

For more than 150 years, Canadian General-Tower (CGT) has stood at the forefront of advanced material science and precision manufacturing. While CGT’s specialized divisions lead global advancements in automotive interior fabrics, swimming pool liners, and technical coated textiles, Goliath Roofing Systems channels that deep chemical engineering and polymer expertise directly into the commercial building envelope.

Operating as CGT’s dedicated commercial and industrial roofing arm, Goliath builds on over five decades of pioneering single-ply PVC manufacturing - a proven legacy that has supported more than one billion square feet of roofing installations across North America. By uniting CGT’s long-standing industrial foundation with purpose-built waterproofing technology, Goliath delivers premium roofing membranes engineered to safeguard high-value commercial assets for decades.

Harnessing Multi-Industry Material Science

Goliath’s core strength stems from the shared technical heritage across CGT’s varied divisions. Since its founding in 1869 manufacturing wagon parts, CGT has continually diversified, pioneering convertible tops for the Ford Model T, high-durability automotive seating, and precision geomembranes before entering the roofing sector in the 1970s. As a specialized division, Goliath draws directly on this institutional knowledge in polymer stabilization, fabric coating, and industrial weatherproofing, formulating commercial membranes with the precision and tight tolerances demanded by high-stress automotive and manufacturing environments.

The Canadian Manufacturing Advantage in Cambridge

Manufactured inside CGT’s primary facility in Cambridge, Ontario, Goliath holds the distinction of being the only PVC roofing membrane produced domestically in Canada. Housing the roofing division within CGT’s established production hub gives architects, consultants, and contractors direct access to regional supply chain reliability. This direct vertical integration ensures end-to-end quality control from raw resin compounding through final extrusion, while eliminating cross-border logistics hurdles and supporting skilled Canadian manufacturing jobs.

For Goliath, being Ontario Made means more than a manufacturing location. It represents a long-standing commitment to quality, innovation, and supporting the industries which rely on dependable roofing solutions.

Key Benefits of Goliath PVC Roofing Membranes:
